Answer:

perimeter = 322.5 ft ( to the nearest tenth of a foot)

Step-by-step explanation:

Length the length of the sides of the square be L

Area of a square = L²

∴ 6,500 = L²

L = √(6,500)

L = 80.6226

Next Let us calculate the perimeter

Perimeter of a square = L + L + L + L = 4L

perimeter = 4 × 80.6226

Perimeter = 322.4904 ft

perimeter = 322.5 ft ( to the nearest tenth of a foot)

<em>N:B rounding to the nearest tenth of a foot is same as rounding to 1 decimal place.</em>

Which transformation will map figure Honto figure H? (1 point)

podryga [215]

Answer:

2) Vertical translation of 10 units

Step-by-step explanation:

Given

H and H'

Required

Which maps H to H'

First, we pick the coordinate of any point on H

$H(x,y) = (4,2)$

First, we pick a corresponding coordinate on H'

$H'(x,y) = (4,-8)$

The above coordinates show that H and H' are not a reflection of one another because neither of the x or y coordinates negate one another.

By looking at the coordinates of H and H, we have:

H: $x = 2$ and H': $x = 2$ --- The same x coordinates

H: $y = 2$ and H': $y = -8$ --- Different y coordinates

The difference between the y coordinates is:

$Difference = H(x) - H'(x)$

$Difference = H(2) - H'(2)$

$Difference = 2 - (-8)$

$Difference = 2 +8$

$Difference = 10$

Hence,

<em>2) Vertical translation of 10 units </em> is correct.

Two classmates, Annie and Whitney, plan to meet in the computer lab to type up their research papers. Annie can type at a speed

madam [21]

The page count will be 10 when the two students will reach the same count.

Step-by-step explanation:

Given,

Typing speed of Annie = 3 pages per hour

Pages already typed by Annie = 4

Let,

x be the number of hours.

y be the total pages typed.

y = 3x+4 Eqn 1

Typing speed of Whitney = 1 page per hour

Pages already types by Whitney = 8

y = 1x+8 Eqn 2

For same number of pages;

Eqn 1 = Eqn 2

$3x+4=1x+8\\3x-1x=8-4\\2x=4$

Dividing both sides by 2

$\frac{2x}{2}=\frac{4}{2}\\x=2$

Putting x=2 in Eqn 1

$y=3(2)+4\\y=6+4\\y=10$

Putting x=2 in Eqn 2

$y=2+8\\y=10$

The page count will be 10 when the two students will reach the same count.
